Paul i will look up some sections for you,And get back.
The directories mostly used .
Post office directories
kellys directory
There are a few more
Ref to the Apprenticeship,Will have to check it out
May also be worth contacting churches for a Baptism Cert in Plymouth.As he was born Pre registration period
It Could take time as several churches.
The london Archives,Hold most parish records,but im not sure about plymouth.
IF he was registered pre 1837,the record would be held in Bishops Transcripts.
School registers can often help to,its finding them also
Will get back as soon as i can find anything PAUL
